Thanks EA37TS and Baseman for you comments and continual support.
As far as batteries, I have four 12V 100AH AGM batteries wired in Parallel.
I wired in Series because a panel has a Optimum Operating Current of 9.36A Four panels in parallel could reach 36-38 amps (on a perfect day. That exceeds the amp capacity of my 10 AWG wire from the panels to the controller. I am now reading 94 volts and less than one amp. I had expected the 90ish volts output but expected 80-10 Amps.
Later today I will recheck the panel wiring to see if in fact my adult grandsons wired it properly in series. If that checks OK I will do a change to parallel or a series parallel. My solar controller output feeds into the inverter and batteries.
A question to you experts. If the batteries are fully charged, will the panel amp output decrease?
